ELECTRIC 011mm CLOCK.

Application filed May 20,

To all whom it may concern:

Be it' known that I, ALBERT BRUNNER, a citizen of the United States, residin at Santa Barbara, inthe county of Santa @arbarn. and State of California, have inventednew and useful Improvements in Electric Chime Clocks, of which the following is a specification.

This invention is an electric chime clock and has for its object the provision of a clock .construction provided with audible means for indicating the hour-and fractions thereof if so desired these audible means being electrically actuated.

It is a further object of the invention to provide a construction of this character in which the electrically actuated movement of the controlling mechanism for the audible indicating means is arranged to wind the main spring of the clock so that manual winding of the clock is avoided.

More specifically, the invention contemplates the employment in a clock of a con trollingdrum periodically partially rotated by an electric motor, preferably, at every quarter hour the. rotation of this drum being adapted to wind the main spring'of the clock and also actuating the hammers for a set of chimes so as to play the chimes at the quarter hour. The controlling drum is also arranged to actuate the hammer of a gong so as to strike the hour.

The invention will be readily understood from the following description of the accompanying drawings, in which Figure 1 is a front elevationof the clock, partly broken away, and with the outer casing and dial of the. clock removed.

Fig. 2 is atransverse section on the line 2-2 of Figul.

- spring of the clock carried in said drum.

The controlling drum is shown at 7 as a hollow drum having end plates 8 and 9 fixed thereto, the latter of which is, preferably, spaced inwardly from the end of the drum to provide a recess in which the main spring of the clock is received. The drum is journaled upon an arbor 10 secured to the rear frame plate 2 by a screw 11, this arbor, preferably, terminating at the end plate 9. An annular flange 12 is fixed upon the end late 9 in spaced relation between the Wa l of drum 7 and theaxis thereof, this flange extending-fron end wall 9 to the plate'6. The

main spring of the clock has its convolu-' tions received in the annular space thus formed surrounding the axis of drum 7, this spring which isshown at 13 being, prefer-i.

ably, a relatively long spring with its outer end restlng against t e flange 12 and yieldably frictionally held against said flange.-

The inner end of the spring is fixed to a square collar 14 which is received over the squared end 15 of an arbor 16 extending into the recess provided for the spring and journaled in the plates 3 and 6.- The outer end of this arbor projects beyond the front plate 3 and has the minute hand 17 of the the hour hand of the clock is not shown, but

it will be understood that the latter is mounted upon arbor 16 and connected with the clock train 18 in any usual manner.

The electrical means for rotating drum 7 may comprise the following mechanism:

A gear 20 is fixed upon the outer surface of drum 7, preferably, in rear of wall 6 and this gear meshes with a pinion 21 fixed up on a shaft'22 extending rearwardly beyond end wall 2 and, preferably, journaled in said end wall and in wall 6. A worm wheel 23 is fixed upon the rear-end of shaft 22, this worm wheel being arranged to mesh with a worm 24 fixed upon a shaft 25 extending downwardly to the base of the clock. The upper end of shaft 25 is, preferably, jour naled in a bracket 26 secured to the end wall 2, this bearing for the shaft25, preferably,

, permitting of slight lateral swing of shaft 25 .in said bearing. The lower end of shaft 25- is journaled in a plate 27 adapted to move laterally relative to the base of the clock and being connected by a spring 28 shown as a leaf spring 'with a block 29 fixed upon the base of the clock. A friction wheel 30 is fixed upon shaft 25, preferably, adjacent its lower end, and this friction wheel is arranged to be frictionally engaged by the shaft 31 of a suitable electric motor 32 mounted in a recess 33 in the clock base and having its shaft extending upwardly above the clock base along side the frictional wheel 30. The spring 28 is so arranged as to yieldably urge the bearing 27 of shaft 25 toward the shaft of motor 32 so that shaft 25 will be yieldably swung laterally in its bearing bracket 26 so as to urge the friction wheel 30 into intimate frictional engagement with the shaft of the electric motor.

By this arrangement it will be seen that when the motor is running the friction wheel 30 will be rotated and as a consequence the drum '7 will be rotated. This rotation of drum 7 is arranged to be in a clockwise direction, and the frictional engagement between flange 12 and the outer end of the main spring of the clock will cause the spring to be wound when the controlling drum is thus rotated. By this arrangement it will be seen that the main spring will always be wound, but that excess Winding of the spring Will be prevented by the frictional engagement between flange 12 and the end of the spring which will permit slipping of the flange past the end of the spring without winding the latter when the spring is tightly wound.

The electrical circuit through motor 32 may be provided by a usual contact plug 35 having the usual Wires 36 leading to any convenient plug, not shown, which is, preferably, arranged to be inserted in either a usual electric light socket or a usual house wall plug. The contact plug 35 may be received within a socket 37 in the side of the clock base, this socket having a plug 38 with which plug 35 is arranged to make electrical contact and being connected by the wires 39 with the terminals of the electric motor 32.

Rotation of the controlling drum 7 is arranged to actuate chime mechanism for striking the quarter hours and a gong mechanism for striking the hours. As an instance of this arrangement a chime set comprising the chimes 4:0, 41, 4C2 and a3 may be sup ported in a bracket 4E upon the clock base, these chimes being adapted to be struck by hammers 45 carried upon hammer rod which are secured to levers i? journaled up on a rod 4-8 which extends from front to back of the clock frame adjacent the outer surface of drum 7. The levers r? have their ends opposite the hammer rod carrying ends arranged adjacent the surface of drum 7 so that pins projecting from the drum surface in alinement with the respective levers 47 will swing the levers upon their pivots when engaged by the pins in alinement with the respective levers so as to strike the re spective chimes. A rod 48 extends from back to front of the clock frame beneath levers 47 to form a stop for limiting the downward swing of the levers.

The pins arranged to engage levers l? are shown at 49 arranged in circumferential lines around the drum, one of said lines of pins being arranged to engage each of the levers l7 when the drum 7 is rotated. T he pins in the respective lines of pins for the respective levers are arranged one beyond the other circumferentially around the drum so as to cause the levers to be successively actuated in such order as to play any de sired tune upon the chime set. The pins controlling the playing of the chime set are arranged around a substantial portion of the circumference of drum 7 with the ends of the series of pins spaced from one another circumferentially of the drum to provide a space in a complete rotation of the drum during which the chimes will -not be played. The gong for striking the hour is arranged to be struck during this portion of a rotation of the controlling drum for which purpose a series of pins 50 are arranged circumferentially around the drum in this circumferential blank space left upon the drum between the ends of the series of pins 49. The pins 50 are arranged in twelve circumferential rows around the drum 7 each successive row of pins from the outer end of the drum across the latter toward the pins 49 containing one pin less from twelve to one.

Actuating mechanism for the gong of the clock which is adapted to strike the hour is arranged to .be shifted relative to the drum at each succeeding revolution of the drum, denoting the passage of one hour, so

.as to successively bring the actuating mechanism into alinement with succeeding rows of the pins 50. Each of the pins in a row are arranged to engage the actuating mechanism for the gong so as to strike the gong, and it will thus be observed that by shifting the actuating mechanism at hour intervals into alinement with succeeding rows of pins containing a number of pins greater by one,

the actuating mechanism will be operated to cause striking of the gong anumber of times arranged to indicate the hour at succeeding hourly intervals.

The gong for indicating the hour is shownas ausual coiled metallic strip 52 secured at one end as by .a screw 53 to the frame of the clock. A hammer 54 upon a hammer rod 55 is arranged to strike the gong. The hammer rod 55 is fixed to an arm 56 which is j ournaled upon the rod 48, preferably, at the end thereof adjacent the front plate 3. A second arm 57 is, preferably journaled upon rod 48 at theopposite end thereof and adjacent arms 47, and a rod 58 is shown as connecting the two arms 56 and 57. The hammer 54 is normally held in contact against gong52 as by a leaf spring 59 having-one end fixed'to the clock frame and its opposite end resting upon arm 56 for yieldably swinging the hammer into contact with the gong. When rod 58 and the arms 56 and 57 are swung upwardly by means of the pins 50, as will now be described, the hammer 54 is swung away from the gong and then released so as to strike the gong by the action of spring 59.

The actuating connection between pins 50 and rod 58, preferably, includes two guide rods 60 extending from front to rear of the clock frame above rods48 and 58. A sleeve 61 is slidable along these guide rods, this sleeve having a slot 62 in its lower end in which is received a lip 63 upon a trip 64 which is journaled upon rod 48. One end of trip 64 is adjacent the surface of drum 7 so as to be engaged by the pins 50 during rotation of the drum for swinging the trip upon its pivot. The opposite end of the trip is notched as shown at 65 to receive the rod 58 in said notch. By this arrangement it will beseen that when trip 64 is actuated rod 58 will be swung upwardly and thereby swing hammer 54 away from its gong. As each succeeding pin in a circumferential row upon the drum surface passes trip 64the hammer 54 will be free to be swung so as to strike its gong, as previously described; The stop rod 48v extends beneath the arms 56 and 57 for limiting the downward movement thereof when rod 58 is thus actuated. Thus it will be seen that'the gong 52 will be sounded a number of times equal to the number of pins in the row of pins with which the trip 64 is alined.

At each revolution of drum 7 which will be at intervals of one hour, the sleeve 61 is shifted along guide rods 60 a distance equal to the distance between adjacent rows of pins 50. The sleeve 61 engaging the lip 63 of 'tripf64 will thus also shift trip 64 -at inter vals of one hour so as to be successively engaged by rows of pins one greater in number until the row of pins containing twelve pins engages the trip 64. During the succeeding revolution of drum 7 the sleeve 61 and trip 64- are returned along guide rods 60 and rod 48 into alinement with the first row of pins 50 containing only one pin .and the operation of the gong striking mechanism is then repeated.

-The means for, shifting sleeve 61 along its guide rods, preferably, includes a spring 68 shown .as a coil spring and surrounding rod 48 between arm 56 and trip 64. -This spring is arranged to yieldably urge sleeve 61 and trip 64 along guide rods 60 and rod 48 into position with trip 64 in alinement with the first row of pins 50 containing one pin. A sleeve 70 is journaled above sleeve. 61, preferably, upon one of the cross rods 4. this sleeve having a toothed wheel 71 fixed thereon and also having a cam-surface 72 formed thereon. A pin 73 projecting upwardly from sleeve 61 is arranged to be engaged by the cam surface 72 which is so constructed as to shift sleeve 61 along its guide rods a distance equal to the distance between adjacent rows of pins 50 at each partial rotation of sleeve 70. The sleeve 70 is arranged to make twelve such partial rotations during each complete rotation of the sleeve, the cam surface 72 being providedwith a straight return surface 74 extending the length of 0am surface-72 for permitting return movement of pin 73' and sleeve 61 underthe impulse of spring 68 after a complete rotation of sleeve 70. A guide 76 is, preferably, arranged adjacent pin 73 for guiding the movement of the latter and the sleeve 61 along the guide rods 60.

At each complete rotation of drum 7 the sleeve 70 is arranged to make one of its partial rotations. For this purpose the toothed wheel 71 is provided with twelve 10b equally spaced teeth 77 which are arranged to be successively engaged by a pin 78 upon the surface of drum 7 so as to cause a partial rotation of wheel 71 and sleeve 70 each time the pin 78 comes opposite the toothed wheel .71. The movement of wheel 71 and sleeve 70 at each engagement by. pin 78 is limited to a one-twelth rotation of the wheel and sleeve by a leaf spring 79 fixed to the clock frame and having its swinging end abutting 7 against the wheel 71 between adjacent teeth.

By this arrangement, at each partial rotation of wheel 71 the spring 79 will ride over a tooth 77 into the space between next adjacent teeth so as to yieldably engage the wheel to prevent further rotation thereof until the next succeeding engagement of a tooth of the-wheel by pin 78.

As previously stated the drum 7 is arranged to make one complete revolution during each hour, this revolution. of the drum being divided into four partial rotations at the respective quarter hours. The drum, being at rest at the beginning of an hour, is

&

quarter hour for engaging chime levers 47 by the first portion of the circumferentially extending series of pins 49; the drum then remains at rest until the half hour when it is again partially rotated, preferably, for a somewhat longer partial rotation than at the quarter hour so as to play the chimes for a somewhat longer period; the drum then again is at rest until the three-quarter hour when the drum is partially rotated to cause a succeeding somewhat longer portion of the series of pins 49 to engage chime levers 47 for playing the chimes for a somewhat longer period of time than at the half hour. In like manner the drum will then remain at rest until the end of the hour when it will this last partial rotation'of the drum the remaining portion of the series of pins'49 will engage the chime levers for playing the chimes for a somewhat longer period of time than at the preceeding playing of the chimes, and as soon as the pins 49 have passed beyond lever arms 47 the pins are arranged to engage trip 64 for striking the gong 52. The number, of times which the gong is struck will depend upon the position of trip 64 along rod 48 which is arrangedto be changed at each succeeding hour, as previously described.

After pins 50 have thus passed beyond trip 64 the pin 78 is arranged to engage toothed wheel 71 for causing a one-twelfth rotation thereof, as previously described, and the drum will then come to rest, a revolution of the drum having been completed when pin .78 has thus passed a tooth of wheel 71 and the beginning of the series of pins 49 being then again in position to actuate the chime levers 47 at the start of the next revolution of drum 7.

The mechanism for causing partial rotations of drum 7, as thus described, may comprise the following mechanism:

A rock shaft 81 is journaled in a sleeve 82 which, preferably, projects rearwardly from the top. of the front frame 3. The rear end of this rock shaft has a lever arm 83 projecting laterally therefrom above drum 7, and the opposite end of the rock shaft at the front of the frame 3 is provided with an actuating rod 84 extending downwardly ad acent the arbor l6 upon which the minute v hand 17 is mounted. A disc 85 is fixed upon arbor 16 in rear of minute hand 17, this disc being provided with four equally spaced cam surfaces 86 arranged to be successively engaged by the end 87 of rod 84 so as to cause the rod 84 to be swung upwardly during each quarter hour as the rod end rides over one of the cam surfaces 86, and then to permit downward swinging of rod 84 at' the end of each quarter hour when the cam surface 86 passes beyond the rod end 87 to permit movement of the rod end downwardly along the radially extending straight surface 88 of the disc 85 which is provided between the end of one cam surface 86 and the beginning of the next adjacent cam surface 86.

By this arrangement it will be seen that the disc 85 making one complete revolution with the minute hand 17 during each hour will cause an upward swing of rod 84 during each quarter hour and a downward swing of said rod at the end of each quarter hour. The rod 84 being connected to rock shaft 81. and the latter having the lever arm 83 fixed thereto will cause a similar movement of the lever arm 83. A finger 90 is pivoted to the swinging end of lever arm 83 so as to depend from said lever arm into position to be engaged by stops formed upon the surface of drum 7. The pivot 91 for this finger is arrangedat one side of the longitudinal center of gravity of the finger so that the finger will normally depend from lever arm 83 with its longitudinal axis extending through the point: 92 of the finger inclined to the perpendicular. A. slot 98 is provided in the finger in which is; received a pin 94 carried by the lever arm 83 so as to limit the swing. of the finger upon its pivot.

A rod 95 projects laterally from rock shaft 81 and then extends downwardly to a position adjacent a contact post 96 carried upon the base of the clock. This post is suitably electrically insulatedfrom the clock frame and is arranged in' the electrical circuit through the motor 32. The electrical circuit through the motor is, preferably grounded upon the clock frame so that when rod 95 is actuated through rock shaft 81, so as to make electric contact with contact post 96. the circuit through the electric motor will be closed for causing rotation of drum 7 and when rock shaft 81 is swung so as to break the contact between rod. 95 and contact post 96, the electrical circuit through the motor will be opened for stopping the motor and thus bringing the drum 7 to a state of rest.

Pins 98 are arranged around the surface of drum 7 in alinement with finger 90 so as to engage the finger and swing arm 83 up wardly for breaking the electrical circuit to the motor and thus bringing the drum to a state of rest. Four or these pins are provided around the circumference of drum 7 so as to bring the drum 7 to a state of rest after the playing of the chimes at each quarter hour. The relative position of the pins around the circumference of drum 7 will be understood by reference to Fig. 4.in which the drum is shown in position just after the striking of an hour, the beginning of the series of pins 49 being adjacent the chime levers 47, and the first one of the series of pins 98in a counter-clockwise direction around the drum 7 engaging finger 90 so as to raise the latter and thus swing arm 83 upwardly and break the electrical circuit thrdilgh the motor. p

The pin 98 is provided with an inclined contact surface 99 so arranged as to engage finger 90 as the pin is swung toward the finger when 'drum 7 is rotated, and slide the point of the finger across the inclined surface for pivotally moving the finger from a position in which the longitudinal axis of the finger is inclined rearwa-rdly relative to the direction of movement of drum 7 into a substantially perpendicular position as shown in Fig. 4. This pivotal movement'of finger 90 will cause pin 94 to abut against the upper end of slot 93 and thereby swing arm 83 upwardly and break the electrical connection between rod 95 and contact post 96. The drum 7 will thus be in a state of rest in this position with the point of finger 9O resting upon the pen 98'. The parts of the mecha nism are so arranged that when the drum and finger 90 are in this position the end of rod 84 will be received in one of the depressions at the beginning of one of the cam surfaces 86 of disc 85. It will be understood that when in this position the minute hand of the clock is at the start of a new hour;

During the next quarter rotation of arbor 16 and the minute-hand, the end of rod 84 will ride over the cam surface 86 and thereby swing arm 83 upwardly. This will cause an upward movement of. finger 90 until its point 92 is free of pin 98. The pin 90 will then swing into an inclined position upon its pivot'91 so that its point 92 extends in rear of pin 98. As soon as the quarter hour is reached the end of rod 84 will slide along the straight surface 88 of disc 85 to the start of the next cam surface of the disc. This will cause a downward swing of arm 84 and a consequent rocking of shaft 81 to swing rod 95 into electrical contact with contact post 96, this swinging movement of the rock shaft being permitted by the disengagement of finger 90 from pin 98, as previously described.' As soon as the circuit through the electrical motor is thus closed, drum 7 will be rotated..as previously described, for playing the chime set until the next pin 98 around the circumference of the drum in a counter-clock direction engages the point of finger 90. The inclined surface 99 of this pin will engage finger 90 so as to swing the latter, as previously described, and again break the electrical connection between rod 95 and contact post 96. The drum 7 will thus be again brought to a state of rest.

In similar manner at the half hour and at the three-quarter hour the drum 7 will be partially rotated in like manner. At the three-quarter hour the drum will be rotated a distance equal to the distance between the last one of the series of pins 98 and the first one of said series in a counter-clockwise direction around the drum to again bring the parts to a state of rest at the beginning of the next succeeding hour. The pins 98 are unequally spaced around the circumference of drum 7 with the space between succeeding adjacent pins of successively increasing length for causing the succeeding partial rotations of drum 7 to be of increasing length for actuating the chimes and the gong of the clock, as previously described.

It will be understood that the pins 78 controlling the hourly shifting of the gong striking mechanism is arranged upon the circumference of the drum 7 between the last one and the first one of the series of pins .98 in a counter-clockwise direction upon the drum so as to cause shifting of the hour' striking mechanism during the last partial rotation of the drum in an hour after the striking of the gong mechanism for that hour. i

It will be observed that the construction as thus described provides a drum having a plurality of pins around the circumference thereof controlling chime striking mechanism, and a series of pins upon the circumference of said drum controlling gong striking mechanism for denoting the hour.

The pins controlling the gong striking mechanism are arranged in twelve circumferential rows upon the surface of the drum with succeeding rows having a number of pins one less in number from twelve to one. The controlling drum is arranged to make four partial rotations during an hour, each succeeding partial rotation being of increasedlengthl. During each of these partial rotations the chime controlling pins are arranged to actuate thechimes for causing the chimes to play for an increased length of time at each succeeding quarter hour. Aft-er striking of the chimes during the last partial rotation of the drum in an hour, one of the rows of gong controlling pins is arranged to engage the gong striking mechanism for sounding the gong a number of times'equal to the number of pins in said row. During this last partial rotation'of the controlling drum in an hour and after striking of the hour a shifting pin upon the surface of the drum is arranged to engage shifting mechanism for shifting the gong striking mechanism from. alinement with the row of gong controlling pins into alinement with the next adjacent row containing a number of pins greater by one. Thus it will be seen that at each succeeding hour the gong will be struck a number of times adapted to denote the hour.

It will also be observed that the clock construction provides means for winding the main spring of the clock by the partial rotations of drum 7 which are in turn controlled by an electric motor. Thus it will be seen that the clock will be wound at all times without necessitating manual Winding thereof. 1
